Yuav Siv Tangential Flow Membrane Filtration li cas los qhia cov qauv
Thaum cov qauv ntim loj (ntau pua ml lossis txawm tias nce ntxiv), koob lim tsis tuaj yeem ua tau raws li lub sijhawm pom, lossis tus nqi siab vim nquag hloov cov lim. Tangential flow membrane filtration tuaj yeem siv los qhia meej cov qauv.
Dab tsi yog tangential flow filtering?
Tangential flow filtration yog hais txog txoj kev pom nyob rau hauv uas cov kua ntws kev taw qhia yog perpendicular mus rau kis tau tus mob. Piv nrog rau lub kaum sab xis tuag, cov kua dej kev taw qhia nyob rau hauv tangential flow filtration yog parallel mus rau daim nyias nyias, uas tuaj yeem ntxuav tsis tu ncua ntawm cov deposits ntawm daim nyias nyias, thiaj li yuav txo tau qhov txhaws. Phenomenon, uas ua kom cov kev kho mob ceev thiab prolongs lub sij hawm kev pab cuam ntawm daim nyias nyias.
Ob qhov xov xwm tsuas yog siv hauv tangential flow filtration: hollow fiber thiab membrane ntim. Hollow fiber muaj qhov tshwj xeeb qhib channel thiab nruab nrab shear quab yuam, uas yog qhov tsim nyog rau kev ua cov qauv nrog cov ntsiab lus siab, siab viscosity lossis shear rhiab heev. Cov txheej txheem nthuav dav thiab pom tuaj yeem ua tiav zoo los ntawm kev siv hollow fiber hauv cov qauv ua ntej chromatographic sib cais.
Hollow fiber yog siv los ua kom pom tseeb thiab pom. Nws tsis yog qhov tsim nyog los tshem tawm cov hlwb lossis cov khoom ntawm tes los ntawm centrifugation ua ntej, uas yog, hollow fiber tuaj yeem siv ncaj qha los qhia E. coli lysate yam tsis muaj hollow fiber. Lub fermentation broth secreted thiab qhia los ntawm mammalian hlwb los yog poov xab tuaj yeem qhia ncaj qha yam tsis tau tshem tawm cov hlwb.
